drm/i915/dsi: don't pass arbitrary data to sideband

commit 26f6f2d301c1fb46acb1138ee155125815239b0d upstream.

Since sequence block v2 the second byte contains flags other than just
pull up/down. Don't pass arbitrary data to the sideband interface.

The rest may or may not work for sequence block v2, but there should be
no harm done.
